America gave the world George W Bush and we have given them, as co-presenter of this rainforest-based fiasco, Myleene Klass. Seems a fair swap to me. Dubbed one of "The Hosts So Mediocre I Shall Not Write Their Names" by Entertainment Weekly, Klass demonstrates just how consummate Ant and Dec are as she provides commentary on the (bushtucker) trials and tribulations of actors Lou Diamond Phillips and Stephen Baldwin (now a born-again Christian), Sanjaya Malaker, contestant on the sixth series of American Idol, and plasticised former model Janice Dickinson. How the not-so-mighty have fallen.

Celebrity MasterChef8pm, BBC1

With faces you'd never get tired of smacking, Gregg Wallace and John Torode return with yet more celebrity barrel scrapeage and meals as appetising as egg noodles with pesto sauce and a salad that looks like rabbit vomit. Among those competing for an accolade that might lead to offers of opening supermarkets in the suburbs are Jan Leeming, Jayne Middlemiss, Rosie Boycott (who's surely slumming it) and Hotel Babylon's Michael Obiora, who "really wants to win". Let's hope, then, that he's better with a whisk than he is at picking scripts.

Living With Monkeys9pm, BBC1

Not to be confused with I'm a Celebrity, part two of the African adventures of primatologist Dr Julie Anderson and "the help", hunky Guy Grieve, continue apace. With the latrine dug, rainwater gathered and a right big cen-tipede got rid of, they focus on the inevitably elusive, red-capped mangabey monkey. Not quite so elusive, unfortunately, are an irate elephant and a silverback gorilla that makes a bear with a sore head look as cute as a kitten.

Eleventh Hour9pm, Living

With the eleventh hour of Eleventh Hour upon him - the series has been axed in America - Rufus Sewell appears to have adopted a nothing-to-lose, hell-for-leather approach to his performance as brilliant professor Dr Hood. Hence, as Texans are afflicted by a mysterious thirst for violence - which brings us back to Dubya, does it not? - he too begins to exhibit odd symptoms which necessitate a lot of "mad" acting that stop just short of foaming at the mouth.
